Mumbai : Three sets of equipment for the Kudankulam Nuclear Power Project (KNPP) in Tamil Nadu have been shipped to India, KNPP’s Russian state-run equipment suppliers and technical consultants Rosatom said on Friday.
The equipment, shipped out by Atomenergomash, the machine-building division of Rosatom, includes moisture separator-reheaters and high pressure heaters for KNPP unit 3, as well as spare parts for the scheduled maintenance of reactor coolant pumps at the already commissioned units 1 and 2, a Rosatom South Asia statement said here.
Three sets of moisture separator-reheaters for the power hall of the third unit have been shipped to India. These are designed for drying and reheating of moist steam and the equipment is included in support systems assuring turbine unit functioning, Rosatom said.
Two high pressure heaters for the turbine hall of the third unit of KNPP have also been shipped.
“The welded vertical apparatus is intended to feed water heating through condensation of steam,” the statement said.
“The total weight of the equipment for KNPP unit 3 is more than 1,000 tonnes. In total, there will be eight sets of moisture separator-reheaters and high pressure heaters.”
Besides, spare parts shipped for the reactor coolant pumps of the functioning units 1 and 2 include bearings, thrust rings and electromagnets. These are used to pump water around the primary circuit to remove the heat generated in the reactor core, the statement added.
The Kudankulam project envisages the construction of six reactors of 1,000 MW capacity each, the first two of which have already been commissioned. Four other units are in various stages of implementation or planning.

Kudankulam n-plant
By Biswajit Choudhury,
Rostov-on-Don (Russia) : The steam generator for the third unit of the Kudankulam Nuclear Power Project (KNPP) in Tamil Nadu is three months away from completion at the Atomenergomash factory around three hours drive from here, according to its Director, Maksim Jidkov.
Leading a party of Indian journalists on a tour of the facilities of this manufacturing arm of Russian state atomic energy corporation, Rosatom, Jidkov pointed to a generator vessel mounted high in the gigantic workshop measuring 300,000 sq mt. Rosatom are the equipment suppliers and technical consultants for the KNPP, the first two units of which have already been commissioned.
Being one of Russia’s biggest industrial complexes, Atomenergomash has 6 million sq mt of production facilities in this area of southwest Russia, in another part of which, at Sochi on the Black Sea, Prime Minister Narendra Modi met with Russian President Vladimir Putin on Monday without a prior agenda, “to further strengthen the special and privileged strategic partnership between India and Russia”, according to a PMO statement.
According to Indian officials currently in Russia, given that the unofficial agenda of the Modi-Putin meet in Sochi was to discuss the situation developing out of the US withdrawal from the Iran nuclear deal, Indo-Russian cooperation in nuclear energy was bound to have figured in the talks.
“The manufacture of the steam generator for KNPP-3 is at an advanced statge and only the last 3 months are remaining of a process that takes two years,” Jidkov said.
“The relationship with India is very important to us. The KNPP contsruction will improve our relations and we hope to have many more projects in India,” he added.
Atomenergomash Chief Executive Nikipelov Andrey said at Rosatom’s just-concluded 10th Atomexpo conference at Sochi that the transfer of technology for the third and fourth units of KNPP would start by the end of this year and the company hoped to finish the work by the end of 2019. He also hoped to sign the agreements for Kudankulam units 5 and 6 before the end of this year.
The KNPP’s 1,000 MW each units 3 and 4, being developed by the Nuclear Power Corporation of India (NPCIL), are expected to become operational by 2021.
Jidkov said that the company has a current order book of $60 billion and has set up units in various countries creating a nuclear capacity of 66,000 MW worldwide. Its equipment are currently in operation in 20 countries.
Atomenergomash has exported to Germany, France, China, India, Hungary, Bulgaria, Belarus, Turkey, Iran, Finland and the Czech Republic, among others.
Parent company Rosatom has many firsts to its credit like the first nuclear power plant at Oblelinsk (Russia) in 1954, the first experimental fast-neutron reactor in 1964 and the first nuclear plant in the Middle East in Bushehr (Iran) commissioned in 2011.
Besides nuclear equipment, Atomenergomash produces thermal power machinery, metallurgical, mining, oil and gas production and processing systems, including ready for use plants for deep processing of petroleum, equipment for the construction industry, for sea water desalination plants, containers for transportation and disposal of nuclear waste and biomass energy units, among others.
The firm manufactures the entire package of products for the nuclear island, including the reactor assembly, steam generator, the main circulation pump and the main circulating pipeline.
Some of the products manufactured by the company include refuelling equipment, both dry and wet spent fuel storages, depleted uranium and lead shieldings, condensers, cranes and lifting equipment, specialised doors, heat exchangers, pool water purification systems, pressure vessels, storage tanks, pumps, nuclear steam supply systems, reactor control rods, reactor internals and reactor pressure vessel seals.
The huge production hall opens on one side to the company’s own mooring berth on the Tsimlyansk Reservoir, which allows shipping bulky and heavy products. After being transported by barge over the reservoir, the shipments take the Volga-Don Canal on to the Baltic Sea port for their onward overseas journey.
Rostov, on the Don river, has for centuries been a major shipping lane connecting southwestern Russia with the north. With the construction of the Volga-Don Shipping Canal in 1952, Rostov-on-Don became a port of five seas – the Black Sea, the Sea of Azov, the Caspian Sea, the White Sea, and the Baltic Sea.

Kudankulam n-plant
Chennai : The first 1,000 MW atomic power unit at the Kudankulam Nuclear Power Project (KNPP) restarted generation after completion of refuelling on Tuesday, said an official.
“The first 1,000 MW atomic power unit was synchronised with the grid between 6.30 a.m and 7 a.m. today (Tuesday). The power generation is around 300 MW,” the official told IANS.
According to him, some tests have to be done as the unit was refuelled.
The power generation would be increased in a gradual manner, he added.
The first unit was shut down on April 13 for annual maintenance and refuelling.
Every year, one third of the reactor’s 163 fuel assemblies, or 54 assemblies, are replaced.
This was the second refuelling cycle for Unit 1.
Meanwhile, the second 1,000 MW unit that was shutdown on August 4 due to hydrogen concentration problem in stator is yet to restart.
India’s atomic power plant operator Nuclear Power Corporation of India Ltd (NPCIL) has two 1,000 MW nuclear power plants at the KNPP built with Russian equipment.
Kudankulam is in Tirunelveli district around 650 km from here.
